[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment of a moisture-proof valve-controlled water meter, comprising a water meter housing 1 and a water meter housing cover 2. One side of the outer side of the water meter housing 1 is fixedly connected to a water outlet pipe 9, and the other side of the outer side of the water meter housing 1 is fixedly connected to a water inlet pipe 15. A mounting plate 11 is provided on the top of the water meter housing cover 2, and a breathable box 19 is provided at the bottom of the mounting plate 11. A threaded groove 18 is provided inside the mounting plate 11, and a cover plug 12 is threadedly connected to the inner wall of the threaded groove 18. A rotating plate 13 is fixedly connected to the outer side of the cover plug 12. A plurality of bolts 14 are threadedly connected to the interior of the mounting plate 11 and the breathable box 19. Both sides of the outer side of the water meter housing cover 2 are fixedly connected to a fixing block 5, and two slide grooves 16 are provided inside the fixing block 5. Disassembly components are provided on both sides of the outer side of the water meter housing 1, and the water outlet pipe 9 and the water inlet pipe 15 are both provided with flanges 10. A dial 4 is provided on one side of the top of the water meter housing cover 2, and a display 3 is provided on the other side of the top of the water meter housing cover 2.

[0032] Specifically, the design of the water inlet pipe 15 and the water outlet pipe 9 allows the water meter to be directly connected to the pipeline during installation without the need for additional adaptation or modification, thereby improving installation efficiency. The ventilation box 19 is equipped with a desiccant that can absorb moisture from the air inside the water meter, further maintaining the dryness of the internal environment of the water meter. This is particularly important for ensuring the normal operation of the water meter's internal electronic components, measuring mechanism, and other precision components. The design of the mounting plate 11 allows the ventilation box 19 to be easily disassembled and replaced. Through the threaded connection between the threaded groove 18 and the cover plug 12, the user can easily unscrew or tighten the cover plug 12 to open or close the access port of the ventilation box 19. This design makes replacing the desiccant in the ventilation box 19 simple and quick, improving the convenience of maintenance. The threaded connection ensures a stable connection between the cover plug 12 and the mounting plate 11. Even under slight vibration or impact from the external environment, the cover plug 12 will not easily loosen or shift. The threaded connection creates a tight seal between the cap 12 and the threaded groove 18, effectively preventing moisture, dust, and other foreign matter from entering the water meter, ensuring a dry and clean internal environment. The design of the rotating plate 13 allows the user to easily open and close the cap 12 by rotating it, without the need for special tools, improving ease and efficiency. Multiple bolts 14 are threadedly connected to the mounting plate 11 and the vent box 19, ensuring a secure connection between them. This design ensures that the vent box 19 is securely mounted on the water meter cover 2, preventing it from loosening or falling off. The vent box 19 can also be removed by removing the bolts 14 on the mounting plate 11, making it easy to clean and maintain. The display 3 provides real-time data updates and dynamic information, including water flow rate, accumulated water consumption, and valve status. This allows users and managers to stay updated on the latest status of the water meter, facilitating timely adjustments to water use plans and water resource management. The dial 4 can intuitively display the water meter reading, allowing the user to see the current water consumption at a glance.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The disassembly assembly includes two connecting plates 17. The outside of the two connecting plates 17 is fixedly connected to the outside side of the water meter housing 1 at the corresponding position. The bottom of the connecting plate 17 is fixedly connected to a plurality of springs 7. The other end of the spring 7 is fixedly connected to a connecting plate 8. The top of the connecting plate 8 is fixedly connected to two sliders 6. The outside of the slider 6 is slidably connected to the inside of the connecting plate 17. One end of the slider 6 matches the inner wall shape of the slide groove 16, and the slider 6 is plugged into the slide groove 16.

[0034] Specifically, the design of the disassembly assembly makes disassembly and installation of the water meter housing 1 extremely convenient. The plug-in fit of the slider 6 and the chute 16, coupled with the retractable spring 7, allows for easy disassembly and installation without the need for special tools, significantly improving work efficiency. The precise fit of the slider 6 and chute 16, coupled with the tight connection of the spring 7, ensures a tight seal during disassembly and installation of the water meter housing 1. The retractable spring 7 not only facilitates disassembly and installation, but also ensures the stability of the water meter housing 1 when closed.

[0035] Reference Figure 5 A sealing groove 21 is provided on the inner wall of the water meter housing 1 , and a sealing plate 20 is fixedly connected to the bottom of the water meter housing cover 2 . The outer portion of the sealing plate 20 is plugged into the inner wall of the sealing groove 21 .

[0036] Specifically, by sliding the slider 6 within the chute 16 and the spring 7 expanding and contracting, the water meter cover 2 can be quickly removed from or installed on the water meter housing 1, significantly reducing the time required for water meter maintenance. The removal and installation process requires no special tools or complex steps; simply push the adapter plate 8. The matching design of the sealing plate 20 on the water meter cover 2 and the sealing groove 21 in the water meter housing 1, as well as the plug-in fit of the slider 6 and the chute 16, ensure the water meter's tightness during removal and installation. This prevents impurities such as moisture and dust from entering the water meter, protecting the safe and stable operation of the meter's internal components.

[0037] Working Principle: Under normal operating conditions, water flows into the meter through the moisture-proof valve, controller, and other metering mechanisms within the meter, where flow is measured, before flowing out through the outlet pipe 9. Simultaneously, the desiccant in the vent box 19 absorbs moisture generated by long-term moisture in the pipes, keeping the meter dry. To replace the desiccant, rotate the turn plate 13 to open the cover 12 and inspect or replace the desiccant in the vent box 19. To inspect the interior of the meter, push the connecting plate 8 downward, allowing the slider 6 to slide within the groove 16 within the connecting plate 17, compressing the spring 7. When the slider 6 is fully released from the groove 16, the meter cover 2 can be completely removed from the meter housing 1. Once maintenance is complete, simply align the sealing plate 20 on the meter cover 2 with the sealing groove 21 within the meter housing 1 and gently press down. The slider 6, activated by the spring 7, automatically slides into the groove 16, allowing the meter cover 2 to be quickly installed.
